Why would this an issue? If you're a man, then your children WILL HAVE your last name whether your last name sounds funny or not. Like Windex said, "the one who plants the seed names the fruit"

As a person belongs to 1.5 generation from the Philippines, there's no way my kids will have their mother's last name. My children will be the one who will carry on my hopes and dreams so all of them will have my last name. I don't care if my wife/partner's last name is Gretzky, Trodeau, Dion, Pearson, Laurier, Mackenzie-King, Borden or whatever.

I hope Windex's post will make you a man enough and make your partner no choice but have her and your kids your last name.

i am the 6th straight first born boy with the same first and last name. 6 generations of 'tranes have ended with me. i am very glad that i had a daughter so that i didn't have to tell my dad that there was no way my son was getting that name to carry on any tradition. all i want is for her (and the soon-to-be kid #2) to strike their own path and be whatever type of person brings them peace and happiness. all naming traditions do is to create an expectation that they will be a chip off the ol' block. one of the last things to hold any relevance in terms of their happiness is my name and my dreams.

I'm the fourth LX, which is why I dropped the A and the E from my name. For the longest time I really bought into the expectations, and wanted to carry on the tradition. But then I really felt pretty freaked whenever my dad tried living vicariously through me. I have to give my parents credit for giving me a ton of personal freedom and responsibility early on though, so that I could see that different paths were there all on my own.

Well my last name is LeSage which has 2 capital letters. Badass in my book.

Just give your kid your last name. People will see 2 different last names and won't think your the father, you will have to explain the name to everyone then you will look stupid.

Why would people care? Sad fact is, I know some people do. I find it amazing that someone would ask another to explain the last name.

My son has my last name. Megan and I aren't married and she made a big ta-do out of it. I was willing to hyphenate. Who cares, y'know? She wanted none of it. So now she yammers on about how he's going to deal with the questions from teachers and kids about why his mom doesn't share his last name. Kids I can understand, because they don't know any better, but teachers? I know this happens because my half-sister has her dad's name and not my moms. Apparently, teachers and parents would quiz her about it. I don't get it. Who has the BALLS to ask such personal stuff? Idiots. So help my God if someone gives my son a hard time.

My wife offered a new name for us to take on as a wedding present, "Loess". As far as I know we're the only two humans in the world with that name (outside of a groovy electro band). It's a geo-archaeological term meaning airborne sand, or a sand formation that is etched and carved by the wind. I love deserts, so it fit.
I'll be driving down the road sometimes and I say my name aloud, and it makes me feel good, positive, and more in touch with who I am.
Our children will have this name, and if they choose, they can discard it or carry it on. Neither of us is close with our fathers so it wasn't hard to switch.

Names are important to me because they carry meaning. Which is why I think it's an important thing worthy of the consideration you're giving it Bjjs.
I hope you find/found something that encapsulates this.
